Question

The solubility of sodium hydrogen carbonate is very low. Why?

Answer 1

@mayankdevnani wud u pls help...

Answer 2

Well, within Hydrogen carbonates HCO3- the bonding is covalent but between Na+ and HCO3- the bonding is ionic.

Answer 3

Okk BT how to remember such things that which bond will be ionic or covalent one...like in dis case how u came up with ionic bond n not a covalent one

Answer 4

hey, i actually don't know! i forgot

Answer 5

but i have a way or understanding to solve this

Answer 6

do i share ?

Answer 7

Okk tell ur way....

Answer 9

since
NaOH+H2CO3=NaHCO3 (First Equivalence point)

We can clearly see that 2nd equivalence point doesn't come,so whole reaction doesn't complete it yet.
So,we can conclude that
\[\large \bf [OH^{-}]_{conc}>[H^{+}]_{conc}\]

Answer 10

from above conclusion,
OH- increases , so Ksp decreases !
therefore, solubility decreases

Answer 11

@samigupta8 understood ?

Answer 12

Shall i tell u the truth?

Answer 13

Ni aaya smjh me ki conclude kse kiya ki oh- >h+

Answer 14

see first equivalence point

Answer 15

for getting neutralized, second equivalence point should come also

Answer 16

second equivalence point, Na2CO3
so conc of H+=conc of OH-

Answer 17

but we need first equivalence point ,
as NaOH is strong base and H2CO3 is weak base

Answer 18

Correct at equivalence point the badic n acidic conc do equalize

Answer 19

ab bheje main utara ?
lol

Answer 20

H2co3 is a weak acid

Answer 21

NaOH is strong base while H2CO3 is weak acid
so at first eq. point, conc of OH- is greater than conc of H+

Answer 22

Correct bt if second agr hota toh woh same conc hoti unki ryt asa kuch hi smjhana chahte ho naa

Answer 23

Second mtlbb secnd equivalence point

Answer 24

yep,smarty

Answer 25

Accha or yeh jo itta bada sara woh solubility k upr bheja tha usme se kaam ka btao

Answer 26

second point,
Solubility and pH
